Applicationy filed February 24, 1911. Serial No. 610,510.

T o all whom it may concern:

Be it known that I, Louis N. JAC'oI, a citizen of the United States, and a resident of the city of Chicago, county of (look, and State of Illinois, have invented certain new and useful Improvements in Resilient Heels, of which the following is a specification.

My invention relates to improvements in resilient heels for boots and shoes and has for its object the production of a heel of this character which will be so constructed that the incorporation thereof in a shoe will render the latter more comfortable and better adapted for use in walking.

.A further object is the production of a heel as mentioned which will be of durable and economical construction, one which may be readily and quickly applied to a shoe and one which will be of great efficiency in use.

Other objects will appear hereinafter.

IV ith these objects in view my invention' consists in a resilient heel characterized as above mentioned and in certain details of construction and arrangement of parts all as will be hereinafter more fully described and particularly pointed out in the appended claim.

My invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a sectional side elevation of a shoe to which is applied a heel embodying my invention, Fig. 2 is an enlarged bottom plan view thereof, Fig. 3 is an enlarged section taken on substantially line :r-ro of Fig. 1, Fig. 4 is an enlarged perspective of the resilient section of the heel, and Fig. 5 is a perspective detail of the spring-carrying plate included in the invention.

The preferred form of my construction as illustrated in the drawings comprises a heel. consisting of a central or intermediate resilient section 1 which is formed preferably of rubber', said section being of the usual peripheral form. Arranged upon the upper and lower sides of said section 1 are rigid sections 2 and 3 respectively, said sections being of less thickness than the section 1 and formed preferably of leather. The sections 1, 2 and 3 are secured together adjacent their peripheries by stitching 1 which extends entirely through the same, as clearly i shown in Fig. 1, the construction being such,

as will 'be observed, that although said sections are securely fastened together the freedom of the intermediate section l for compression is not impaired, the stitching or sewing being flexible to permit of such.

Provided centrally in the intermediate section 1 is an opening 5 extending completely throu h the same, thereby forming an interior c amber in the heel which is closed at its upper and lower sides by the sections 2 and 3 respectively. Arranged in this chamber, that is in the opening 5, at the bottom thereof is a metallic plate '0 which rests directly upon the upper side of the section 3. Said plate is of a peripheral form identical `with that of the opening 5 and of dimensions such that when arranged in said opening, said plate will be securely held therein its engagement with the sides of the opening preventing any relative movement. Arranged upon the upper side of said plate is a compression spring 7 pref erably of the coiled type and conical, the upper end of said sprin resting forcibly against the under side of t e section 2. Provlded upon opposite sides of the plate 6 are ears 8 which are bent into engagement with the lower-most or base convolution of said spring, said ears serving, as will be observed, to securely hold sald spring in position upon said plate, thus preventing relative movement thereof in the heel.

In use, the heel above described is secured to a shoe by means of nails or pegs 9 which extend through only the section 2 of said heel into engagement with the rearmost or heel portion of .the sole 10 of the shoe, the latter being designated as 11. In order to permit of such attachment of the heel, that is of the attachment thereof through the medium of the nails 9 which pass only through the section 2, the sections 1 and 3 are perforated as' at 12 so as to permit of the passage of said nails into engagement with the section 2, as clearly shown in Fig. 1. Were the construction such thatthe nails or pegs-9 projected and engaged all of the sections of the heel, that is 1, 2 and 3, said nails, because of their rigid nature, would impair the freedom for compression of the intermediate section l and thus defeat the purpose of the heel.V With the construction as set forth wherein the Y 5 erably of a durable tenacious leather, secured to the section 3 by means of nails or pegs '14, the latter, as will be observed, projecting onlj7 through said section 3. The section 13 closes the outer endsof the passages 12 and is provided to lreceive all wear to which'the heel is subjected when in use. l? A heel of the construction as set`forth is i durable andfeconomical, the provision of the resilient section 1 and the Spring 7 resulting in a heel possessing to a high degree resiliency and durability and in the production of a heel well' adapted to absorb shocks so as to conduce to ease and comfort in walking. The heel because of its simplicity iny construction may be manufactured at a low cost and is adapted to be readily andquickly attached to a shoe for use A While I have illustrated and described the preferred construction for carrying my invention into effect this is capable of variation or modification without departing from the spirit of the invention. I, therefore, do not wish to be limitedto the precise details of constructionrrasset forth but desire to avail myselfof such variations and modifications 'as come within the scope of the appended claim. p

Having described my invention what I claim vas new and desire to secure by Letters Patent is: j

A resilient heel, comprising upper and lower leather sections; an intermediate rubber section, said sections being of similar peripheral forms and sewed together adjacent their peripheries, said intermediate section being provided with a medial oblong opening; a metallic plate of the same form and iitted into the bottom of said opening upon Louis N. JAoBI.
